AIR-WARMING FURNACE.

SPECIFICATION forming part of Letters Patent No. 511,164, dated December19, 1893.

Application filed July 7, 1893. Serial No. 479,847. (No model.) 7

To a whom it may concern.-

Be it knownthat we, JOSEPH SOHILL, JOHN SGHILL, and PETER SoHILL,citizens of the United States, and residents of the city of Crestline,in the county of Crawford, in the State of Ohio, have invented a new anduseful Air-Warming Furnace, of which the following is a correctdescription.

The invention relates to certain improvements in that class of heatersor hot-air furnaces designed for use in dwelling houses and otherstructures, in which the heater or furnace proper is inclosed, except inits front central portion, by a casing which forms in connectiontherewith, an air chamber, which receives currents of fresh air at ornearitslower extremity and which discharges the same warmed to thedesired degree, through suitable openings in the upper extremity of theair casing, into metallic conduits, through which they are conveyed tothe various portions of the structure which are to be warmed.

A leading object of the construction which we have devised, and whichwill now be described,is to provide at small expense a novel series orsystem of fines, for the discharge of the products of combustion; and anovel means for assembling the same ll} connection with acombustionchamber, of steel, in which necessity for perforating thebodyof the com bustion chamber in the act of securing the parts together isavoided, and whereby the circulation is sufiiciently restricted andcontrolled without theaid of a damper.

Another object is the provision of means for presenting to the action ofthe incoming and ascending air currents, an extensive radiating surface,or series of surfaces, in the interval between thebody of the combustionchamber and the bodyof the air casing, in

connection with the supports of such parts. The invention consistsin thenovel parts, or combinations of parts which will now be described indetail, and which will be specifically set forth in the paragraphs whichfollow such detailed description.

In the accompanying drawings which constitute a part of thisspecification,Figure 1 represents a top plan view of the combustion andair-warming chamber section of the fur; face. Fig. 2 is a verticallongitudinal central seotion,as in the line :r--:c of Fig. 1. Fig. 3

is an irregular horizontal section,as in the line y-y of Fig. 2. Fig. lis a transverse central section,as in the line c-.e of Fig. 3. Fig. 5 isa rear elevation, and Fig. 6 is a central section, of the auxiliary orintermediate flue plate, detached.

It will be seen that the base-plate or lower head a, of the combustionand air chamber section a, is composed of an inner ring 03, an outerring a and intermediate connecting arms a, which serve as bearings forthe lower extremity of the detachable radiating plates of; and that atsuitable intervals the inner ring has perforations 13 to receivesecuring rods 19, by which when the parts are in place, the upper andlower plates are secured together. The upper head Z) is similar in itsgeneral construction to the lower head but the ring 5 connects theexterior arms 17 not to an interior ring, but to a closed head or domebfiwhich constitutes the top of the combustion chamber.Atthefront'thefeedchute f, is secured by its flanges f to the body ofthe inner cylinder or combustion chamber 0, in an ordinary manner.

In the rear of the extremityof the combustion chamber 0, is the smokehood 3, which is of the T-form shown, the open ended arms 3 of the sameextending as shown nearly to the body of the cylinder.

Upon the exterior of the cylinder c,coincident with the smoke opening isfitted the intermediate plate ip, which has raised rim or flange toconstitute a recessed surface, within which is received by its flange (1the diving and out-take fine (I, the lower and discharging end d ofwhich projects outwardly through the opening'in the body of the aircasing cc. Y

The rear opening in thebody of the cylinder 0, is of dimensions sufficiently greater than the corresponding portions of the smoke hood,the diving and out-take fine and the intermediate plate, to permit theflanges of the hood, the diving fine, and the interposed plate to besuitably secured together, without the necessity for perforating thebody of the combustion chamber itself; thereby effecting much economy oftime and labor.

The radiating plates a having been set in place within their bearings,the air casing etc, is byits rear opening, fitted over the project- Iing extremity of the discharging end 61 ,01 the out-take flue, and itsfront is fitted over the I body of the feed=chute. This heing done, the

securing rods are'fixed in place, either'by' heading down, orrby theapplication of suitable nuts.

The provision of the T-arms, upon the retarding-hood and the location ofthe same at a point near the Walls, and near the upper extremity of thecombustion-chamber, prevent a rapidescape of the products of combustion;

and retard the flowof the smoke currents to.

such an extent that the provision of a damper to efiect this purpose isrendered unnecessary. The nature and objects of the invention havingbeen thus described, and the construction and operation of the apparatusin which it is embodied having'bee'u set torth,what is claimed is- 1.The cylindrical combustion-chamber c; the cylindrical air-casing ac; thebase-plate as, having inner ring a outer ring u connecting andsupporting arms a and perforations 132; the upper head I), havingcentral dome b exterior-ring b and the connecting-arms b the detachableplate aipand the secur ing rods 19; in combination; substantially asspecified.

2. In an air-warming furnace, the combination with thecombustion-chamber, of the described smoke-retarding hood and flue,having the inlet branches 3 arranged in theu'pper, rear portions ofsuchchamber, as shown, and the damperle ss diving and out-take flue, betweenthe combustion-chamber and the aircasing and-leading directly downwardfrom tially as and for the purposes set forth.

" 3. In an air-warming furnace, the combination Withthecombustion-chambemof the flanged T-shape'd smoke-retarding hood and thesmoke-retarding hood and flue; 'substanflue therein; the flanged divingand out-take fine, in the encircling air-chamber of the fur pace; andthe recessed or flangedintermeflange of the T-shaped smoke-hood, andflue; I

substantially as set forth.
